Batch And Inline High Shear Emulsifiers And Colloid Mills
Rotor and stator machines that mix, disperse, shear and homogenise viscous liquids and pastes, either in the vessel, in the pipeline or through a mill gap.
The Range
Three Ways To Put Shear Into The Product
The batch emulsifier works inside the vessel, the inline emulsifier sits in the pipeline and pumps while it shears, and the colloid mill grinds between rotor and stator for the finest particle size.
Batch emulsifier
High Shear Batch Emulsifier
Vessel mounted rotor stator emulsifier with four stator options.

Inline emulsifier
Inline Emulsifier
Pipeline mounted emulsifier that shears and pumps at the same time.

- Pharmaceutical manufacturers preparing syrups, ointments and oral liquids
- Paint, ink and coating makers dispersing pigment into a carrier
Problems It Solves
The mixture separates after production
An agitator alone cannot break droplets small enough to stay dispersed. Rotor stator shear reduces droplet size so the emulsion holds.
Powder floats instead of wetting in
Powder and liquid mixing heads pull powder below the surface and shear it into the liquid instead of leaving lumps on top.
Cleaning between batches takes too long
Quick opening construction and hygienic design let the head be opened and cleaned without stripping the machine.
Why This Line
What Is In The Machine
Four Stator Types
Different stators to suit different working conditions, from coarse dispersion to fine emulsification, on the same drive.
Sanitary Construction
All wetted parts in grade 304 or 316 stainless steel with mirror or matt polish to Ra below 0.8 um and a mechanical seal for sanitary operation.
Explosion Protected Drive
Explosion proof three phase motors are available where solvents or flammable product are in the vessel.
Application Scenarios
Where The Shear Goes In
In The Vessel
Batch emulsifier mounted on the tank, shearing the whole batch to a target droplet size before discharge.
In The Pipeline
Inline emulsifier fixed in the line for continuous work, transferring low viscosity material while it emulsifies.
Through A Mill Gap
Colloid mill for wet processing of superfine grain, homogenising, emulsifying, mixing and grinding semi liquids and latex emulsions.

Selection Guide
Picking Between Batch Inline And Mill
Decide Batch Or Continuous
A batch machine treats a vessel of product. An inline machine treats the stream as it passes, which suits continuous lines.
State The Target
Droplet or particle size, or simply the product that has to come out. That decides stator type and number of passes.
Check Viscosity And Volume
Viscosity at process temperature and the batch size set the motor rating and the head diameter.
Confirm Area Classification
Solvent based product usually means an explosion proof motor and the right elastomer in the seal.
Answers
High Shear Emulsifiers FAQ
What is the difference between a batch and an inline emulsifier?
The batch machine mounts on the vessel and shears the whole batch. The inline machine sits in the pipeline, works continuously and also moves the product, which is why it is sometimes called an emulsifying pump.
Which wetted materials do you use?
Grade 304 or 316 stainless steel on all wetted parts, with mirror or matt polish to Ra below 0.8 um.
Can the machine mix powder into liquid?
Yes. A powder and liquid mixing head is available in this line for exactly that duty.
Is a colloid mill the same thing?
No. A colloid mill grinds between a rotor and stator with an adjustable gap for wet superfine processing. It goes further on particle size than an emulsifier head, which is why food, chemical and pharmaceutical plants use it for pastes and fine emulsions.
Can it be cleaned in place?
The design is hygienic with quick opening for easy cleaning. Tell us the cleaning chemistry and temperature so the seal elastomer matches.

The difference is molybdenum and carbon content. What that means on your plant is chloride resistance and how the material behaves after welding.

Choosing A Sanitary Pump That Survives Your CIP Cycle
The pump has to move product gently and then take hot caustic at full flow. Those two requirements pull in opposite directions, and the elastomer usually loses.
